Vision AV-1800 Digital Amplifier

2 x 50W

Out Of Stock!

Vision AV-1800 Digital Amplifier

2 x 50w RMS (at 8 ohms) low impedance digital power amplifier
3 x Stereo inputs / 1 x Stereo Pre-Output / 1 x Balanced Mic input with Phantom Power
Bluetooth Input
IR remote included, RS-232 control

The improved AV-1800 is compact, and has a simple interface with just two dials which are turned to adjust and pushed to switch. It has a selection of inputs - including Bluetooth and a microphone input, making it suitable for meeting rooms, small auditoriums, lecture theatres, school halls, and small churches.

The amplifier can automatically switch to the Bluetooth source when it is paired. Bluetooth can be renamed and the pin changed by connecting to a PC (see software link below).

Microphone Input
It uses a professional XLR connector and the input is “balanced” to eliminate electro-magnetic noise induced on long cables. The microphone input has “Phantom Power” - a voltage which is required by condenser-type microphones such as lectern microphones.

It can be controlled by a control device such as Techconnect Control via IR or RS-232. It also comes with an IR remote control gives the user bass and treble adjustment and direct input selection.

An efficient Digital-class amplifier chip dramatically reduces power consumption especially at rest.

3 x Stereo Inputs
Three stereo inputs accept input from a variety of sources such as computers (via the headphone jack), tablets or phones. 2 of the inputs are via 2-phono (RCA) connectors on the rear panel. Input 3 is via a 3.5mm Minijack connector, and is duplicated on the front and rear panels for easy access.

Line Output
A line-level pre-output on the rear panel bypasses the internal amplifier. It would connect to a larger amplifier or powered loudspeakers. It is post-mix, which means any volume adjustment made on the front panel affects the output level.

If the amplifier senses no input it will automatically go into standby mode. When it senses input it will reactivate. Auto-standby can be disabled.

Mounting Options
mounting hardware is included to allow cable-tying either to a projector ceiling pole, or into a rack.
